v-cmcbfa v sisrsa, or newsman-amass;

To IQZZrwIzom itmayconcern State of Indiana, have invented "new and useful Improvements in; Bicycles, of. which thefollowingtis a specification; 2

This invention relates to ,bicycles-,the ob ect 1n viewrgbelngtoproduce achilds b1- cycle embodying-a cheap and noveljconstruc- I tion o f frame including 1 an extensible seat support forming: impart uof the frame and enaiblingwtlie machinemea one, two. or

more passengers as may be required, the machine being also constructedto ,represent j a motor and tank-t0 makajithe whole re- 3 semble a motorcycle. V a p i I i llVith the above and other ob ,ects 1n vlew,

the invention consists in the novel construci t i tion, combination and arrangement of parts,

as will hereinafter be more fully described,

' illustrated and claimed. o 11 In the accompanying drawings :Figure 1 is a side elevation of abicycle embodying the present invention. Fig. 2 1s a perspec tive View of the frame,showing the driving mechanism and omitting the wheels. Fig. 3 is a fragmentary sectional view of one of the wheels.

The frame of the bicycle contemplatedjiii this invention comprises a top run 1 which is substantially horizontal as shown, and a pairof bottom runs 2 which are spaced a suitable distance apart as shown, theforward ends of the bottom runs being bent upwardly at 3 to form the upwardly inclined forward portions 4: which are connected totheshank 5 of a head tube6 which receives a bolt 7 through which the frame is pivotally connected to the front fork 3 in which the front .or steering wheel 9 is carried in the usual manner. A handle bar 10 of ordinary construction is connected to the headof the front fork 8 to enable the operator to steer the machine, 11 designating the operators seat which is adjustable along the tops run 1 by means ofa combined screw 12 or its equivalent. r

The rear extremities of the parallel bottom runs 2 are providedwith bearings 13 for a rotary reardriving axle 14 on which the rear driving wheels 15 are fastened. The rear axle 14 also has fast thereon a sprocket wheel 16 from which a sprocket on the parallel bottomruns 2 "andis pros vided with the usual jcranksQlfiandpedals The rear end of the top run11 is slip:

.' 24L designates an extens on seat barwhich carries a second or auxiliaryseat 25, for a passenger who rides in rear of the operator of the machine. Theextension seat bar 24:

end portion of the topgrun 5 s em the seat 5. ay be a ju t d o" ny. i ed x en is telescopically or slidably fitted in the rear i rear f h rivers seat 11 andmaybe fixed in such position, when adjusted by .means of a binding screw26 or the equivas mulator. The parallel horizomitot tom runs 2 form an excellent support for an internal combustion motor by means of 'whichthe sprocket chain17 may be driven inlieu of the crank shaft 19 referred to.

27 designates a cross bar fastened to the parallel bottom runs 2 and having its end portions d shed to form foot rests 28 for the rearmostrider who occupies the auxiliary saddle 25. If desired, operating cranks 29 may be fastened on the rotary axle of the front wheel 9 by means of set screws 30. Where the cranks 29 are employed,

another saddle 31 will be mounted upon the top runll and held in placeby means of a clamping screw 32. v v Q In the preferred embodiment of the in- 'vention, each of the wheels is constructed to comprise a hub 33, a rim 3 1- and spokes 35 secured at theirinner ends to flanges 36 at opposite ends of the hub, thespokes' 35 con verging from the hub outward where they are connected to the rim 34c. v

In order to make the machine more attractive to children, anengine 38 is placed in the frame of themachine, thesame ineluding a base 39 and a rear extension 40 to represent a gasol'ene tank; The parts 38, 39

and 40 will ordinarily be pressed out of sheet metal and arevmerely intended, as a representation for the essential parts of an engine. i

41 designates a combined carrier and rest which "is'pivotally connected at 4-2 to rear extensions of the bottom runs 2 so that said carrier and rest maybe moved either to a horizontal pos tion as shown in Flg. 1 where it may be sustained by a staycha n 43 or to a substantially vertical positionwhere it will act as a rest and hold the rear wheels 15 clear of the ground.

The seats 11 and 81 are rendered detachable from the top run 1 by means of the U- shaped clips 43 which are adaptedto straddie and pass over the top rim being held securely in place when adjusted by means of the bolts "12 and 32. -A band pulley d is provided onthe-rear axle 14, the same being of the grooved type to receive a driving belt or band which may be used to' operate any toy while the bicycle i's'atr'es't and supported upon the combined carrier and rest i1, thus adding to the utility and attractiveness ofthe toy bicycle.

, 7 Copies of this patent may be obtained for It is to be understood that the pulley 44 is operated by the same driving mechanism including the cranks 21 and pedals 22 as used-in propelling the machine.

lVhat I claim is "1; In a bicycle, a frame embodying a top run; parallel bottom runs in spaced relation to each other and having their forward portions deflected upwardly and connected to the forward extremity of the top run, a rear fork extending from the top run downwardly to the rear extremities of the bottom runs rear axle bearings at the points of junction of the bottom runs and rear fork a rotary driving axle journaled in said bearings, driving wheels fast on the opposite ends of said axle, a crank shaft, sprocket wheels on said crank shaft and reardriving axle, anda sprocket chain running around said sprocket wheels.

2. A bicycle embodying a frame comprising a tubular horizontal top run, a drivers seat adjustable lengthwise of said top run, an extensionseat bar telescopically fitted in said top run, means for fixing the adjustment of said seatbar,'and an auxiliary seat carried by said extension seat bar.

In testimony whereof I aifix my signature in presence of'two witnesses.
